In Florida 90 degrees heat I had some minor skin scrapes. I purchased this charging dock as a gift for my boyfriend, so that he could charge his Samsung Watch and Buds. so this replacement knob is going to almost cost me the price of a full rack?? Figured I better put the money towards a Thule rig so this doesn?t happen again. I guess that is not a terrible thing if you are worried about it coming apart in your bag or something. I was very pleased with the stand and the excellent delivery service. Functions the same way my regular PS4 controller does, plus I like how the Shoulder buttons have a bit more click which is really satisfying. Out of the box, it did turn on, i. The order arrived as expected (actually earlier than expected). The even signal is very enjoyable , and the isolation works great . I had no issues with the flip-flops.
